A real-time refrigerator monitoring solution was created using a temperature sensor and microcontroller to track internal temperatures. When temperatures fall outside the safe range, the system sends email alerts within one minute. A web interface displays live readings, records anomalies, and logs alert history. Tests showed it reliably detects deviations, helping protect food, vaccines, and biological samples. With simple hardware, easy deployment, and email alerts, it is suitable for home, medical, and logistics use, offering scalable protection against unnoticed refrigeration failures.
